Wood type and application method can vary coverage.

Osmo Decking Oils protect, maintain and beautify the wood surface, producing a smooth satin finish which is extremely water resistant and dirt repellent. The microporous finishes are based on natural vegetable oils and allow the wood to breathe and helps regulate the moisture content reducing swelling and shrinkage, the finish will not crack, flake, peel or blister.

Note: 007 is a dual purpose product and may show 'Teak Oil 007', although it is usable as a clear decking oil. This is confirmed by the text on the back of the tin, second paragraph, in the 'recommended use' section. Please be advised that 125ml tins are printed in German only. For application instructions refer to the overview below.

Osmo decking Oil is water-repellent and reduces the risk of swelling and shrinkage. Can be over-coated with a single coat of Osmo Anti Slip Decking Oil 430 if required.

Note: The clear Osmo 007 Decking Oil does not offer any UV resistance so although the wood will be protected from moisture, cracking, splitting and warping, it will not prevent decked areas from turning grey or silver over time.

Decked areas must be clean, dry and frost-free. Old paints, varnishes and other surface coatings must be removed by sanding. Old applications of oil based treatments or stains need to be cleaned or lightly sanded. If sanding, use a 120 to 150 grit sandpaper and remove all traces of surface dust.

New wood: If possible apply first coat on all sides of the wood before installation. Hardwoods with an especially high content of oil, leave to weather for about 2 to 3 months (in winter up to 5 months) or wipe over with White Spirit to degrease the surface.

Hard wood with a high content of natural wood extractives needs to weather off (for at least 4 weeks) before the initial treatment or to be cleaned with Osmo Brush Cleaner and Thinner (degreaser). Resinous wood e.g. Larch or Douglas Fir needs to weather off for at least 6 weeks. Pressure impregnated wood, Massaranduba, Bangkirai or Garapa need to weather off for at least 3 months.

Use Osmo Wood Reviver Power Gel to clean the wood surface and remove grey wood cells before renovating the area.

For additional protection against blue stain, rot and mildew, pre-treat with Osmo WR Base Coat 4005 or with Osmo Wood Protector 4006 (biocide-free).

Osmo Decking Oil is ready to use straight from the tin and can be applied with a brush or cloth. Stir well before application and use a brush or soft lint free cloth to apply a thin, even coat of oil along the wood grain. Wipe off any excess when finished and leave to dry. Apply second coat as above or alternatively, apply a single coat of Osmo Anti Slip Decking Oil 430 if required.

The type and age of the timber can have a dramatic impact on how much oil the wood needs. As an example, softwood decking that is old will probably require more oil than a relatively new hardwood deck that probably still retains a fair amount of natural oil.

To test how much oil your decking needs, apply one coat, allow to dry, then apply a droplet of oil in a corner. If the droplet of oil soaks into the wood then a further coat can be applied. Repeat this process until the droplet of oil sits as a bead on the surface of the wood and no longer soaks in to the timber. This is an indication that the timber has absorbed as much oil as possible and doesn't require any more.

There is no need to thin this product prior to application. Routine cleaning can be done with Osmo Decking Cleaner 8025 or Ronseal Decking Cleaner.

Application brushes and equipment can be cleaned with white spirit.

This product can be stored up to 5 years or more if the tin is full and tightly closed. Store in dry place. If thickened by frost it will regain its normal consistency under normal temperatures within 24-36 hours.

If there is an amount left over after application, it is recommended that the remaining oil is poured into an alternative container of the same volume e.g. 1 ltr of oil left pour into a 1 ltr drinks bottle or other secure container. By filling the alternative container to the rim and securing an air tight lid, the remaining oil will stay in good condition for much longer than if left in a container half filled with air.

  • Keep out of the reach of children.
  • Do not fill into containers normally used for food and drink.
  • Work in areas with good ventilation.
  • Do not apply in the presence of naked flames, hot surfaces or unprotected electrical equipment.
  • In case of contact with eyes rinse immediately with plenty of water.
  • Contains 2-butanonoxime. May produce an allergic reaction.

Osmo decking oil is safe for human, animal and plant when fully dried.

Q. Is there a specific time on how long an oiled deck will last before it needs re-oiling?

A. Unfortunately not. The reason for this is that the elements such as wind, rain and sun all have a degrading effect on the amount of oil in the wood. For that reason, every deck will be different because of location, shelter, weather patterns and general wear and tear.

Q. Is Osmo Decking Oil UV resistant to protect the colour of the decking?

A. Osmo decking oil is available in three variations, clear, black and grey. While the black and grey colours do offer UV resistance due to the pigments suspended in the oil, the clear variation does not. Decking treated with the clear version of Osmo Decking Oil will therefore be susceptible to the natural grey / silvering of the timber over time.

In short, the darker the colour, the better the UV protection. In the case of this product, grey offers more protection than clear and black offers more protection than grey.

Q. I ordered a tin of Osmo Clear Decking Oil and received a tin labelled 'Osmo Teak Oil 007' is this correct?

A. Indeed it is. Osmo sell their Teak Oil 007 as a dual purpose product as it is perfect for Teak and decking, especially dark exotic hardwood decking which tends to be made from very dense and naturally oily woods.

Allow 10 to 12 hours drying time between coats and the final finish. Drying times may vary depending on the decking type, air temperature and humidity.

Good stuff by Duncan Smith

Goes on well and looks great when done. The price is hefty but hopefully will be worth it, time will tell. It lets the grain show through and looks much better than the 'film' coating type of deck stain that I've used in the past.

Excellent quality but coverage not accurate by Calum Sinclair

Having used Osmo oil before we knew this would be excellent quality, and we were correct. The colour is strong and the oil gives a very durable, waterproof finish which water runs off. If applying to new wood however, the coverage on the tin is very misleading and you will need far more than stated so be sure to order plenty to give enough for two coats.

All instructions were plain and simple to follow. The product itself did not present a problem and the finished surface,texture and colour were what I was seeking. I used it as the base coat for the compatible non slip wearing coat and the completed projected was a success.

Great product, good coverage and deck is looking pukker! by Gero Montagna

I used this oil based on my gardener recommendation who laid hardwood decking in my garden. I was told it was more expensive but it's worth every penny in the long run. I spoke to a member of staff from Wood Finishes Direct and they sent me enough to complete 2 coats, I've been left with 1/4 of a can which I was happy with. I used the clear oil which does have a slight tint to it so it has made the deck slightly darker. I loved the depth of colour when the deck was wet and this oil gives it that same effect but permanently. Water just sits on top now and dries off in the sun. Recommend that it's applied very thinly.

Top product great finish by Mark Hopwood

Having used several different oils in the past, this is far superior to any other brand. Yes it seems expensive but in this case you do get what you pay for. It has tremendous coverage which is easily applied. I used a large stiffish brush which gave a thin even coat. The colour finish is very natural. I was applying larch colour onto softwood pressure treated decking planks. Service from these guys is great as usual. Thoroughly recommend product and customer service.

Great on Ipe by Roisin Gleeson

Jet washed Ipe and let it dry for a couple of days then used 2 coats of this oil which brought it back to the colour it was when installed. Started a third coat but it didn't sink in and darkened it even more but preferred just the two coats for protection. It's good- I might try the grey colour next time it needs done which hopefully will be in two/three years.

Fantastic by "Honey Dew" DIYer

We all have a "Honey Do" list. "Honey do this for me. Honey do that for me" Well my Honey Do was to oil the deck. Having bought less expensive, more volume products last year, we returned to an old favourite. We have used this oil before both internal and external and you cannot beat this oil. Yes it is vastly more expensive than others but you get what you pay for as we have discovered. The only thing that I would say is that "Clear" is not clear. It will satin your woodwork but in a wonderful colour. This oil actually feels right. Only another 472 Honey Do's to do!

Product a little darker than expected even though Osmo market it as clear by T Christie

The quality of the product cannot be faulted but the colour was darker than expected especially as it is marketed as clear and for that reason alone I would not order again. This is obviously a matter of taste rather than a reflection on the product which was very good and easy to apply.
